Kendall and Carlos show off some pretty impressive tattoos during this sit-down with MTV.

Kendall just got his fourth tattoo recently of a sugar skull on his upper right arm. Carlos got a massive tribal tattoo on the right side of his torso last month.

Carlos' ink, which he says has many meanings (but doesn't share any!), took three hours to complete. Part of it, unfortunately, was painful, as he explains, "So for the first hour and a half, I had numbing cream. I didn't feel it. And then we went and did a radio visit, and I came back, and the next hour and half was pretty terrible."

Carlos also shared that his dad was kind of "iffy" about the tattoo, until he explained what it all meant, "and that kind of made him a little over the edge, like 'ok cool.'"

Will they be getting more tattoos? Kendall says his fourth is "definitely not the last one."

James and Logan don't seem as on board with the whole tattoo thing, with James only committing to a henna tattoo!
